FAQs About Replacing HVAC Systems

Buying a new HVAC system is a significant investment and working with the right company may be the most important decision in the buying process. As an experienced and reputable HVAC company, you can rest assured that TradeCraft Mechanical will guide you through the replacement process with honesty and integrity. That being said, you shouldn’t start the process without asking the proper questions. That’s why we have put together the below frequently asked questions we receive when replacing HVAC systems.

1. What size unit is right for my home?

The size of your unit determines energy efficiency and the overall comfort of your home. An HVAC unit’s capacity must reflect the size and configuration of your home. A unit that is too big won’t run as often as it should and will provide poor temperature and humidity control. A unit that is too small will struggle to keep all of the rooms in your home at the desired temperature, and run constantly, especially in extreme weather.

To determine the proper size that is best for your home, a contractor needs to measure the house completely – get all of the insulation R-values, window types, orientation, infiltration rate, duct leakage, and more. Using all of those calculations they can input the measurements into a software to determine the actual heating and cooling loads for your home.

2. Can I keep my current ductwork?

The distribution system in your home plays a large role in the functioning of the HVAC unit. Many duct systems don’t move as much air as they should because of ducts that are too small, kinked, too long, or have other types of constrictions. The condition of your ductwork should be evaluated during your replacement estimate.

3. What should I look for in a contractor?

Selecting the right contractor is critical. Ask about their licensing and qualifications to make sure they are appropriately licensed and adequately insured. You should also ask about the size of your contractor’s staff to ensure there are adequate workers to not only install your system but also to respond to service calls. Finally, be sure to ask if they are familiar with the brand of equipment you want to purchase.

4. What is the installation timeline?

If you’re planning on purchasing an HVAC system to replace a malfunctioning or broken unit, you probably want the new system in place as soon as possible. In many cases, however, installing an HVAC system isn’t a quick process. With electrical, plumbing, and ductwork components to coordinate, the installation process can easily take more than a day. If the system is larger or requires significant ductwork updates, the process could take up to several days.

5. What is the total cost?

It is recommended that you obtain three written estimates prior to choosing a contractor to work with. Ask them each to explain their cost breakdown including the system pricing, the labour costs and charges for anything extra like a new thermostat or air quality components. The actual price of installation varies from one HVAC contractor to another and equipment costs vary from brand to brand. Make sure to ask about any rebates or special offers that are being promoted that you may be able to take advantage of.

6. What about maintenance?

All HVAC equipment requires routine maintenance and having a maintenance agreement helps assure your system is ready no matter the weather situation. Understand what guarantees, warranties and follow-up services are available by asking if the contractor offers a maintenance service agreement.

7. When is the best time to replace my HVAC system?

HVAC companies are usually busy repairing and replacing furnaces and heat pumps during the winter months and summer is the peak season for air conditioners. There are usually significant savings involved if you buy a new system right after summer. Similar to stores’ after-Christmas sales, many HVAC companies and manufacturers offer sales and rebates on units and installation throughout the Autumn season.

If your HVAC system is old, inefficient or in need of repair, it might just be the time to consider replacing it. While it is a big investment initially, it’s also a great opportunity to improve your home’s comfort, air quality, and energy efficiency.
